SPECIFICATION forming part of Letters Patent No. 783,639., dated February 28, 1905.

Application [iled April 2l, 1904. Serial No. 204,277.

To all m7112171/ '/l; rim/y concer/t.'

Be it known that l, S'numnm H. GU'rnuIn, acitizen of the United Sta-tes, residing in York township, in the county ol Statie rd and State ot Kansas, have invented new and useful lhnprovements in Windmill and Pump Couplings, ol which the 'Following is a specilication.

My invention relates to pump connections, and particularly to connections between the recimocating rod ot' a wind-wheel and the pump-rod and lever or handle of a manual lever-pump.

llhe object ot' my invention is to provide a connection that will be automatic in action, thereby obviating the use of bolts, wrenches, etc., which is necessary in applying' the connections most generally used.

Furthermore, the object et' the invention is to produce a coupling that can. be operated automatically by either the reciprocating rod of a wind-wheel when it is desired to operate the-pump by wind-power or when the reverse action is desired and the operator wishes to connect the pump-handle with the pump-rod the manipulation of the pump-handle will throw the pump-rod out of engagement with the reciprocating rod of the wind-wheel and at the same time form a connection between the pump-handle and pump-rod.

Finally, the object oi. the invention is to produce a connection that is comparatively simple in construction, strong, and eilicient for the purpose for which it is designed.

1t is usually desirable to employ pumps in connection with wind-wheels, and in case the wind is not sniiicient to drive the wheel and it becomes necessary to operate the pump by means of a manual lever or handle the reciprocating rod oi the pump must be disengaged from the reciprocatingl rod of the wind-wheel and connected with the pump-handle. ln making the change from one power to the other it has generally been the practice to use separate and distinct means, and it 'frequently happens that both the reciprocating rod of the windwheel and the pumpshandle are left connected at the same time. This obviated by my invcntion, as the construction is such that either one (the reciprocating rod ol the wind-wheel or the pump-harulle) must be disconnected, it being impossible by the construction oli my invention to have both connected at one and the same time. Should theopcrator inadvertently leave the pump-handle comiected with the pumprod and the windwheel should be started before the disengagement ol'l the handle, the accidental breakage ol.3 any ot' the parts are thus avoided.

In describing my invention in detail relierence will be had to theaccompanyingl d rawings, 'forming parto'll this specification, and in which like numbers denote correspoinling parts in the several views, and in which-- Figure 1 is a perspective view ol lny invention. Fig. 2 is a crosssection ol the cylinder. Fig. 3 is a sectional view of the split collar attached to the reciprocating' rod oli' the windwheel.

In the drawings, 'l denotes a pump of any ordinary construction having' a cylindrical top, over which a ring Q is seated. 'lhe ringl 2 has secured thereon two vertical extending arms 3 and 3', which diverge in the center, but Contact at each end, the opposite ends o'lE the vertical arms being secured to a divided collar il, said divided collar having' a central aperture in the periphery, of which l YForm two spiral grooves 5 and 5. A cylinder (5, provided with an approximately rectangular shaped ap erture extending longitudinally thereo'lE and. provided with spiral threads 7` and 7 on its outer surface, is supported by the divided collar 4, and the spiral thread is held in engagement with the spiral grooves carried by the collar. The cylinder is also provid 3d with extensions 8 and 8 on each end, thereby preventingl the accidental disengagement olf the cylinder with the divided collar.

On the pu1nprod 9, which has a flattened portion at one end, two pins l0 and 1,0 are secured, said pins extending outward from one side and being oppositely disposed from each other.

The pump-handle llV is carried by a link adapted to rotate in the collar 1i, through which the pump-rod reeiprocates when the pump is operated by means of the wind-wheel. The collar Meis made larg'e enoug'h to permit of a lost motion sufficient to allow the bool;- shaped projection to come in engagement with the pin 10.

Upon the end of the reciprocating' rod of the wind-wheel is a collar 16, having' an eX- tension 17 with a slanting edg'c, by which the collar is secured to the reciprocating rod of the wind -wheel by means of bolts or rivets. rl`he collar 16 is provided with a slot 18, eX- tending'vertically the length of the collar, and this vertical slot has a cut-away portion 19, which is adapted to engage the pin 10, carried by the pump-rod, when it is desired to operate the pump b v means of the wind-wheel. A split ring' 20, having an extension at each end, is carried by the collar 16. The slot 21 of the splitring'QO is adapted to reg'ister with the slot 18 of the collar 16.

The operation of my device is as follows: The device is secured upon the top of a pump by means of the ring, andthe pump-rod reciprocates when disconnected from the pumphandle through the collar 1-1, and when disengaged from the reciprocating' rod of the wind wheel the pump rod reciprocates through the split collar carried by the ring' 20. It will be observed that by raising or lowering the cylinder a partial rotation is caused by the spiral threads carried by the cylinder. Then the operatm' desires to connect the pump-handle to the pump-rod, the handle is pressed downwardly along' the pump. By this action the collar 14 is forced up against the cylinder, and the cylinder is forced upward and at the same time is partially rotated. By the `partial rotation of the cylinder the pumprod is turned far enough to disconnect pin 10 from the slot 19. The handle is then lifted, and the hook-shaped projection of the collar 1-1 is brought in engagement with the pin, and the pump can then be operated by the pumphandle. The handle being thus connected to the pump-rod and t-he wind-wheel being' started, the collar 16, carried by the reciprocating rod, is forced down on the cylinder, and as the cylinder is forced down the same is partially rotate l, and the partial rotation of the cylinder causes the pump-rod to partially rotate, and the pin is disengaged from the hookshaped projection carried by the collar. As

soon as the pin 10 is disengagedfrom the hook-shaped projection the weight of the pump-rod will cause the same to descend until the pin 1() rests on the top of the ring by which the device is secured to a pump. The hook-shaped projection and slot 19 being opposite to each other, it will be observed that.

10 rides down over the slanting edge of the Y collar, thereby twisting' the wind-wheel rod, and as the pin 10 slides into alinement with the slot 19 the spring of the rod, caused by the twisting, will cause the pin 10' to be forced into the slot 19, and the pump will then be connected for operation by the wind-wheel.

Having fully described my invention and the operation of the same, I desire to be understood that while I have described a simple and preferred form of my invention I do not limit myself to` the structural details herein set forth, but reserve the right to any changes, modifications, and alterations within the spirit and scope of my invention and which may be resorted to without sacrificing the utility of the same.

Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. The combination with a pump-handle of a pump-rod and a wind-wheel reciprocating rod a ring seated on the pump and vertical arms carried by the ring', a cylinder supported by the arms, means for giving' a partial rotary motion to the cylinder, a collar having' a hook-shaped projection pivoted to the pumphandle and means for connecting' the pumphandle and pump-rod and the pump-rod and wind-wheel reciprocating rod and means for supporting the handle as and for the purpose set forth.

Q. In a device of the character described, a collar supporting' vertical diverging' arms, a divided collar carried by the vertical diverging arms, a cylinder carried by the divided collar and means on the cylinder for partially rotating the same, a collar having' a vertical slot and an extension carried by the reciprocating rod of the wind-wheel and means carried by the pump -rod for connecting the pump-handle and the reciprocating rod of the wind-wheel and vice versa as and for the purpose described.

3. In a device of the character described, a ring supporting' vertical diverg'ing arms, a divided collar supported by the vertical arms, a cylinder provided with spiral thread on its outer surface supported by the divided collar,
